Description

Technical Field

[0001] This utility model belongs to the field of dental orthodontic instruments, and specifically relates to a bracket with an auxiliary tube. Background Technology

[0002] The simplest existing single bracket consists of a base plate and ligating wings. The base plate is bonded to the tooth surface, and the ligating wings provide archwire ligation and transmit orthodontic forces. The shape of the base plate is similar to the lingual tooth morphology, being roughly rectangular. When applied to the lingual surfaces of incisors and canines, a thinner base plate results in less of a foreign body sensation. For example, CN202420601475.5 discloses a lingual bracket including an integrated base plate and ligating wings. The base plate has a T-shaped structure with a transverse section and a longitudinal section. An auxiliary tube is machined on the surface of the transverse section, and a ligating wing is machined at the end of the longitudinal section. This bracket structure, with its T-shaped base plate, provides transverse and longitudinal references, offering strong directional positioning. The narrowed longitudinal section also avoids interference from the edges of the teeth. However, the auxiliary tube takes up space, and the front end is still relatively thick, causing a foreign body sensation and hindering occlusion.

[0003] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0004] The purpose of this invention is to design an auxiliary tube support groove that reduces the thickness of the auxiliary tube end.

[0005] The technical solution of this utility model is implemented as follows: a support with an auxiliary tube, including a base plate, and auxiliary tubes and ligating wings arranged at both ends of the base plate; characterized in that: the auxiliary tube is an open groove, having a groove body and a groove opening, the width of the groove opening being smaller than the width of the groove body, and the steel wire passing through the groove body can be constrained within the groove opening.

[0006] The cross-section of the groove is a cut circle or polygon.

[0007] The base plate has a T-shaped structure with a horizontal section and a vertical section. The auxiliary tube is located on the horizontal section, and the two sides of the horizontal section are thin edges, which slope from the surface to both sides or become thinner in a stepped manner.

[0008] The starting position of the thin edges on both sides of the transverse segment does not exceed the extension range of the longitudinal segment toward the transverse segment, and the thinnest part of the thin edge is close to the horizontal center plane of the circular or polygonal groove.

[0009] In this invention, the auxiliary tube adopts an open design, which ensures that the orthodontic wire can pass through and be restrained, while reducing the thickness space occupied by the tube wall, greatly reducing the thickness of the auxiliary tube end, reducing the feeling of foreign objects, and improving the orthodontic experience.

[0019] The present invention will be further described below with reference to the accompanying drawings. It should be noted that, without conflict, the following specific embodiments can be arbitrarily combined with the examples or technical features described below to form new embodiments. These constitute preferred embodiments and should not be used to limit the scope of protection of the present invention. Any non-substantial changes or substitutions are within the scope of protection claimed by the present invention.

[0020] Reference Figure 1 and Figure 2 The structure includes a base plate 1, auxiliary tubes 2 and ligation wings 3 at both ends of the base plate 1. The ligation wings 3 facilitate ligation with the archwire and can also be fitted with a bracket wing using a sliding groove 31 in the middle of the ligation wings 3, providing an adjustable ligation groove that can be flexibly combined. In this structure, the auxiliary tube 2 is an open groove with a groove body 21 and a groove opening 22. The width of the groove opening 22 is smaller than the width of the groove body 21, allowing the steel wire to pass through the groove body 21 and be constrained within the groove opening 22. In other words, the auxiliary tube 2 is a non-closed structure, reducing the space occupied by the wall thickness on one side and maximizing the thinning effect, at least by more than 0.1 mm.

[0021] In this example, the cross-section of the groove 21 is a cut circle. Theoretically, a cross-section larger than a semicircle can constrain the passing steel wire. Considering the allowance between the groove and the steel wire, as well as the deformation of the groove material, the width of the groove 22 is not greater than the radius of the groove 21.

[0022] Furthermore, the base plate 1 has a T-shaped structure, with a transverse section 11 and a longitudinal section 12. The auxiliary pipe 2 is located on the transverse section 11, and the two sides of the transverse section 11 are thin edges 111, which slope outward from the surface or taper in a stepped manner; in the illustration, the thinning is stepped. Additionally, the starting position of the thin edges 111 on both sides of the transverse section does not exceed the extension range of the longitudinal section 12 towards the transverse section 11, and the thinnest point of the thin edges 111 is close to the horizontal center plane of the circular or polygonal shape of the tank 21. Alternatively, the two sides can be rounded to further reduce the thickness of the side edges while maintaining design rigidity.

[0023] Reference Figure 3 and Figure 4 The basic structure of the slot is the same as the previous example, except that the cross-section of the slot 21 is a polygon with a cut. Similarly, the width of the slot opening 22 is no greater than the radius of the inscribed circle of the slot 21. This example uses a hexagon, but theoretically, quadrilaterals or larger shapes are also possible. The polygonal structure of the slot 21 facilitates tool entry and machining.
